Acting jobs requiring no experience are entry-level roles, generally non-speaking roles of little overall importance to a production. Your duties and responsibilities as a performer depend on the type of production; if a theater company hires you to perform on stage, you participate in rehearsal activities and performances. Some acting professionals gain experience and build their resume by participating in a drama class that ends with a production. Another option for entry-level actors and actresses is to perform as a character in a theme park or similar venue. Other opportunities include acting in advertisements, student films, or providing voice-overs.
